No due date and sorting
On the web app, items with no due date seem to fall to the bottom of project and label lists. On the iOS (and Android) apps, they seem to appear at the top of these lists by default.
Is this difference intended? Bottom seems to make more sense, as no due date is a handy "someday/maybe" tactic, and those items are better off at the bottom of project and label lists rather than at the top.
Within a project, I can't reproduce it because all tasks in a project are shown exactly as they're placed and there's no option to resort them on the iOS app.
However, I can reproduce this issue on the label list and we will correct it in future updates.
